C rank on the first mission
Took like 18 minutes but that s*** is hard to navigate if you don't already know how it's laid out. I only got hit a couple of times by that shriek area attack from the marionettes in the marionette room, I believe. Ended with health.
I think I picked up like three Blue Orbs, or fragments? I'm not entirely sure..
